Study Finds Variation Within Species is a Critical Aspect of Biodiversity
December 5, 2017 12:12 PM - University of California - Santa Cruz

Concerns about biodiversity tend to focus on the loss of species from ecosystems, but a new study suggests that the loss of variation within species can also have important ecological consequences.

Study of Darwin's finches reveals that new species can develop in as little as two generations
December 4, 2017 08:31 AM - Princeton University

The arrival 36 years ago of a strange bird to a remote island in the Galápagos archipelago has provided direct genetic evidence of a novel way in which new species arise.

On Nov. 23 in the journal Science, researchers from Princeton University and Uppsala University in Sweden report that the newcomer belonging to one species mated with a member of another species resident on the island, giving rise to a new species that today consists of roughly 30 individuals.

When to fish: Timing matters for fish that migrate to reproduce
November 30, 2017 09:35 AM - University of Washington

It’s no secret that human activities affect fish, particularly those that must migrate to reproduce. Years of building dams and polluting rivers in some regions have left fish such as salmon struggling to return to their home streams and give birth to the next generation.

Higher Plant Species Richness May Not Be Enough To Protect Ecosystems From The Worst Impacts Of Climate Extremes
November 29, 2017 11:24 AM - British Ecological Society (BES), SciDevNet

Studies on mild fluctuations in weather have provided support for the idea that higher biodiversity results in more stable functioning of ecosystems, but critical appraisal of the evidence from extreme event studies is lacking.

 

Where Corn Is King, the Stirrings of a Renaissance in Small Grains

To the untrained eye, Jeremy Gustafson’s 1,600-acre farm looks like all the others spread out across Iowa. Gazing at his conventional corn and soybean fields during a visit in June, I was hard-pressed to say where his neighbor’s tightly planted row crops ended and Gustafson’s began.
